Technical Field

The invention belongs to the field of electric digital data processing, and particularly relates to a control method of a sun-shading device in an office.

Background

The core problem of intelligent buildings (or smart buildings) is the intelligent construction of the indoor environment of the building. The key to realize the intelligent construction of the indoor environment of the building is the intelligent control of indoor environment control systems (such as air conditioners, sunshades, lighting, windows and the like).

The premise of intelligent control of the environment control system is the identification of the environmental preference and the regulation habit of indoor personnel. The environmental control behaviors (namely air conditioning behaviors, sun shading behaviors, lighting behaviors, window behaviors and the like) of the personnel are good media for dynamically identifying the preference and the habit, so that the dynamic identification and prediction of the environmental control behaviors are the basis for realizing the intelligent construction of the indoor environment.

Then, the reason why the person performs the sunshade action is complicated. Unlike air conditioning or window activity, people are subjected to both "light" and "heat" to create a sun shade. In addition, there is a proportion of subjective factors, such as the need for visual comfort^[1]. Furthermore, the adjustment of the sun shade by the person is somewhat inert, resulting in a low frequency of sun shade activity. And there is a "contradiction" in the regulation of the sun shade, resulting in the sun shade being present as an "alternative" in most cases^[2]: for example, in cold seasons, a completely pulled-up sunshade screen can bring about the problem of sun exposure to people, but at the same time, the requirement of the people for indoor light environment is more prone to natural lighting, so that a 'contradiction' is brought about, the problem of indoor heat discomfort of the environment can be solved by the people in other ways preferentially, and if the problem cannot be solved or alleviated, the problem can be improved by adopting an 'alternative device' for adjusting sunshade. Finally, the sun-shading pull-down behavior is generated with more obvious hysteresis. Even ifWhen the current indoor photo-thermal environment deviates from the comfortable interval of the personnel, the personnel still have a very large probability of not adjusting the sunshade, but take action after a period of time, and the lag time is as long as 1.5-3 hours^[3]。

In conclusion, the existing sunshade behavior judgment method cannot accurately and efficiently identify and predict the personalized sunshade behavior in combination with the environment of indoor personnel, and further cannot enable environment control to achieve system intelligent control.

Detailed Description

The positive sunshade behavior point and the negative sunshade behavior point related in the embodiment of the invention are specifically explained as follows:

the invention considers that the difference of resident positions of personnel in an office can influence the sun-shading behavior mode, and verifies the sun-shading behavior mode through the form of questionnaire survey. In the questionnaire survey, regarding the sunshade behavior, the questionnaire contents include the determination of boundary conditions such as the orientation of the person-resident position, the orientation of the window with the sunshade closest to the person-resident position, the distance between the person-resident position and the window with the sunshade closest thereto, and the use frequency of the sunshade. The only multiple choice question is to ask the cause of the shade adjustment. In order to obtain a general conclusion about the correlation between the shading adjustment frequency and the position of the person, the questionnaire should cover as many regions and climatic zones across the country as possible.

And finally, 259 effective questionnaires are collected to cover 29 province and city autonomous regions in the country, and each province and city autonomous region has the effective questionnaire number. The questionnaire results are sorted, and the sorted results (as shown in fig. 1) show that the room orientation and the seat orientation of the office where the visitor is located are uniformly distributed, and show that the window which is closest to the resident position of the person and is provided with the sun-shading curtain faces south most, and other orientations are uniformly distributed.

In order to analyze the correlation between the sunshade adjustment frequency and the position where the person is resident, the adjustment frequency in the questionnaire is converted into a numerical value, as shown in table 1. The corresponding value is hardly adjusted to 1, and so on, the corresponding value is often adjusted to 6.

It is to be noted that it is extremely difficult or even impossible to determine in advance the proportions of the various representative populations. If the absolute values of the number of the visitors are directly added when the sun-shading adjustment frequency of each distance interval is calculated, the statistical analysis result deviates from the real distribution. Therefore, the average value is used to describe the sunshade adjustment frequency for each distance interval:

in the formula, F is the average value of the sun-shading adjusting frequency; f is a numerical value corresponding to the sunshade adjusting frequency; n is the number of people corresponding to a certain option; i is a corresponding option of 'sunshade adjusting frequency'; k is the corresponding option of "distance (m) between the person's resident location and the nearest window with the shade".

TABLE 1 Sun-shading adjustment frequency and corresponding numerical value

From the documents [4-6], it is known that human behavior is closely related to seasons. Therefore, the analysis process should distinguish seasons. According to the questionnaire survey issued by the present institute, fig. 2 and 3 show the relationship between the average value of the sunshade adjustment frequency and the distance from the person's resident position to the nearest window with the sunshade screen in summer and winter, respectively.

Linear fitting is performed on the variables in fig. 2 and 3 to obtain corresponding dominant relationships, R, in summer and winter²0.9144 and 0.8616, respectively, preliminarily proving the sun-shadingThe adjusting frequency is in a negative correlation with the distance from the position where the person stays to the nearest window with the sunshade. Through the questionnaire survey, it can be verified that the difference of the resident positions of the persons in the office affects the establishment of the sunshade behavior mode, that is, "the difference of the resident positions of the persons due to indoor layout affects the sunshade adjustment mode of the persons", and "the more distant the persons are from the sunshade, the lower the sunshade adjustment frequency is.

Through further derivation and analysis, the personalized difference of the personnel is not only reflected in the sensitivity difference of the personnel to the continuous stimulation of the external physical environment, but also caused by the difference of the positions of the rooms where the personnel are located: when a person is in a position away from the sunshade screen, the microenvironment around the person is not changed no matter how the sunshade state is changed, so that the person in the position is considered to have no 'requirement' for adjusting the sunshade state, and the sunshade behavior is unlikely to be generated.

Based on the above analysis, the present invention proposes the concept of "positive points" and "negative points" for behavior generation, thereby describing the resident positions of people. For a sunshade act, "a person's resident position that is not affected by a change in the sunshade state" may be defined as "a passive point of the sunshade act"; the "position of a person who is affected by a change in the sunshade status" is defined as "the positive point of the sunshade behavior". If a person is in an active position in a room at a certain moment, the person is considered to possibly generate a sun-shading behavior no matter the person is in a habit type or a preference type, and further personalized behavior identification is needed; if no person in the room is in the active position at a certain moment, the sunshade state is not changed, and the sunshade state does not need to be changed.

In addition, further research on the organized survey results requires first to summarize the types of external physical environment stimuli that cause shading behavior, as to how to determine whether a certain person's resident position is an "active point" or a "passive point" of shading behavior. The invention collects the reasons of the sun-shading behavior by issuing questionnaires.

It can be seen from fig. 4 that the main cause of the shading behavior is the person being stimulated by "light" or "heat" caused by the sun, at least partly due to subjective factors such as "want to look at the scenery outside the window" or "want to adjust the window". Therefore, it can be further inferred that "at a certain time, if a person is stimulated by direct" light "or" heat "from the sun at that position, the position at that time is determined to be" the positive point of the sunshade behavior ", and conversely, the position is determined to be" the negative point of the sunshade behavior ".

In conclusion, glare and direct solar radiation can be used for describing stimulation of light and heat to indoor personnel, so that the two index thresholds at different moments can be calculated, and the type of the point location can be judged.

Because the sun is located in different directions at different moments, the point location type of one station can change along with different time. If the 'positive point of the sunshade behavior' appears in the room at the current moment, the situation that the personnel on the station are influenced by the sunshade state is shown, and a model needs to be called to predict whether the sunshade behavior is generated; if the room at the current moment only has the 'sunshade behavior passive point position', the situation that the personnel in the room at the current moment are not influenced by the change of the sunshade state on respective stations is shown, namely the current personnel do not have 'requirements' on the sunshade device, the sunshade behavior cannot be adjusted, the sunshade state is kept unchanged, and a prediction model does not need to be called.

in order to make the technical means, creation features, achievement purposes and effects of the invention easy to understand, the following describes a control method of a sun-shading device in an office in detail with reference to the embodiments and the accompanying drawings.

< example >

Next, a sun shading device will be specifically described as an example of a sun shading roller blind.

Fig. 5 is a flowchart of a method for controlling a sun-shading device in an office according to an embodiment of the present invention.

As shown in fig. 5, a method for controlling a sunshade in an office includes the steps of:

and step S1-1, acquiring indoor images including all resident stations in a room, and identifying the indoor conditions of the personnel in the room in real time to obtain the identification result of the personnel in the room.

And S1-2, judging whether the person is resident at the station or not, entering S1-3 if the person is resident at the station, and re-entering S1-1 to acquire the indoor image at the next moment and recognize the indoor condition of the person if the person is resident at the station.

And step S1-3, calculating the direct sunlight degree of each resident station by the direct sunlight image according to the station position information corresponding to each resident station and the time corresponding to the indoor identification result of the personnel.

Fig. 6 is a schematic view of a wall azimuth relationship according to an embodiment of the present invention.

The solar direct illumination is calculated by the following steps:

step S2-1, calculating a solar azimuth angle Θ according to the geographical location information of the office and the identification time corresponding to the indoor identification result of the person (the solar azimuth angle Θ is an included angle between the projection of the connecting line between the sun and a certain point on the ground and the south direction, as shown in fig. 6):

wherein alpha is the solar altitude in the geographical position information,the local latitude in the geographic position information; delta is the declination angle in the geographical position information; and omega is a solar time angle corresponding to the identification time.

When the sun is off-east, the solar azimuth angle Θ is negative; when the sun is off-west, the solar azimuth angle Θ is positive.

Step S2-2, calculating a sun wall azimuth angle gamma based on the sun azimuth angle theta and a steering angle psi, wherein the steering angle psi is an included angle between the orientation of the building where the office is located and the south-pointing direction:

γ＝|Θ-Ψ|

FIG. 7 is a schematic diagram illustrating location information of a resident workstation according to an embodiment of the present invention.

And step S2-3, calculating to obtain a value of the resident station influenced by the direct sunlight as the direct sunlight according to the solar wall azimuth angle gamma, the station position information and the room size of the office.

Specifically, taking the station 2 (i.e., the point #2) in fig. 7 as an example, after the daily wall azimuth γ corresponding to the whole office is obtained through calculation, according to the station position information of the station 2 relative to the window and the room size parameter of the whole office, a value of the station 2 affected by the direct sunlight is obtained through calculation and is used as the direct sunlight degree of the station 2.

And step S1-4, calculating a glare value corresponding to the resident workstation according to the weather information of the office and the observation view of the indoor personnel.

Fig. 8 is a schematic view of an observation view of an embodiment of the present invention.

Fig. 8(a) shows the visual effect of human eyes when the window is not aligned, and fig. 8(b) shows the visual effect of human eyes when the window is aligned.

The observation view is obtained according to the position and the direction of the eyes of the indoor personnel, and when the indoor personnel are not directly opposite to the window, the observation view is shown in fig. 8 (a); when the indoor person is facing the window, the view is as shown in fig. 8 (b).

The glare value DGP is calculated by the following formula:

in the formula, E_vIs the vertical illuminance L of the eyeball in the position where the eyeball of the indoor person is positioned_sBrightness of light source in weather information, w_sThe light source solid angle in the weather information, P is the position index of the indoor personnel, and a is the a-th indoor personnel.

In this example, a DIVA insert was used for annual glare simulation. Inputting a weather information file and an observation view (Camera views) where an office is located into a DIVA plug-in, inputting building materials and parameters corresponding to the office, and setting related simulation parameters, such as: people's on-room Schedule (Occupancy Schedule), radiation parameters (Radiance parameters), Adaptive visual comfort (Adaptive visual comfort). Then, the DIVA plug-in is operated to obtain the DGP value in the field of vision of the indoor personnel.

The computing core of the DIVA plug-in (DIVA for Rhino plug-in) is radix, and the radix core uses monte carlo sampling and a reverse ray tracing algorithm, that is, a computing point is determined first, the computing point performs reverse ray tracing on a light source, after limited reverse tracing, computing is performed if the light source is encountered, and zeroing is performed if the light source is not encountered.

The DIVA combines a Radiance core with a Perez all-weather condition sky model and a Tregenza sunlight coefficient method, and realizes annual dynamic light simulation. The solar coefficient is the normalized contribution of the discretized sky or ground segment or preset solar position to the solar energy calculated at each building sensor point. Once generated, the daylight coefficients can be folded with the luminance efficacy and distribution model to compute a time series including the illumination.

And S1-5, judging whether the solar radiation degree is greater than a preset maximum solar radiation threshold, if not, entering S1-6, and if so, entering S1-7.

And S1-6, judging whether the glare value is larger than a preset glare threshold value, if so, entering S1-7, and if not, entering S1-9.

Wherein the glare threshold (i.e., DGP threshold) is 0.35.

The glare perception for different DGP thresholds is shown in table 2.

TABLE 2 Glare perception for different DGP thresholds

When indoor personnel on the resident workstation can perceive the glare problem, the resident workstation at the moment is the active point of the sun-shading behavior.

And S1-7, when the judgment in the step S1-5 is yes or the judgment in the step S1-6 is yes, setting the resident station as a positive sunshade behavior point.

And S1-8, performing personalized sunshade behavior prediction on indoor personnel based on the positive sunshade behavior points to obtain a sunshade behavior prediction result, and controlling the sunshade device based on the sunshade behavior prediction result.

In this embodiment, the result of the sunshade behavior prediction is what gear the office staff corresponding to the resident station will adjust the sunshade roller blind, for example, the fully opened sunshade roller blind is adjusted to the first gear which covers only one fifth of the window, the fully opened sunshade roller blind is adjusted to the second gear which covers only two fifths of the window, and so on.

And S1-9, when the judgment in the step S1-6 is negative, setting the resident station as a passive point of the sun-shading behavior, and controlling the sun-shading device to keep unchanged.

When the resident station is set as the passive point of the sun-shading behavior, the sun-shading device is kept unchanged, and the position of the sun-shading roller shutter is not adjusted.
